Lydia stepped out in London on Tuesday night (9 July) for the launch party of the third series of Dynamo: Magician Impossible.

With everything from off-the-shoulder lace numbers to pretty shifts and fishtail gowns, we reckon this could be a sell-out!
We caught up with Lydia earlier this year for all her fashion and beauty tips - watch video!
